If you used the Desktop program before you may not like the Online version. It has less features and no Forms Mode. All the Online versions do not have the same forms so you may need to upgrade to a higher version. You can only do 1 return. Your return is only saved online so be sure to save both the .tax2024 data file and the pdf file to your computer when you are done. In case you need to amend in the future or if you need a copy to get a loan or something. You might not be able to access your online return when you need a copy.
